Well I have used the Animal Pack (as a matter of fact I still have about 10 packs left in the container ), but anyway..
There are a total of 11 pills, 8 of which are rather...umm...huge.
But if you were to take about 10-12 liver tabs (also made by Universal) per day you would get around the same amount of vitamins.
But one cool thing about the animal pack was seeing my urine come out neon yellow
So I say either Animal Pack or Liver tabs...liver tabs are cheaper.
